D. ln the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to at least 3.
E. Always enable SRTP when configuring an agent phone.
Answer: AC
Explanation:
Guidelines for Agent Phone Configuration
Follow these guidelines when configuring agent phones for Unified CCX agents:
Choose Device> Phone in
Unified Communications Manager Administration. The Find and List Phones window is displayed.
Enter search criteria to locate a specific phone and click Find. A list of phones that match the search criteria is displayed. Click the device name of the phone to which you want to add a directory number. The Phone Configuration window is displayed.
ln the Unified Communications Manager Administration Phone Configuration web page, select the required
Association lnformation (on the left) to get to the Directory Number Configuration web page. On this page, make the following changes:
ln the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to 2 (default is 4) for Cisco Unified lP Phones 7900 Series and 3 for Cisco Unified lP Phones 8961, 9951, and 9971.
Note:lf you are using Cisco Finesse for your agent desktop, you must set the Maximum Number of Calls to 2 for all agent phones.
ln the Multiple Call/Call Waiting Settings section, set the Busy Trigger value to 1 (default is 2).
ln the Call Forward and Call Pickup Settings section, verify that you do not forward any Unified Communications
Manager device to the Unified CCX extension of an agent.
ln the Call Forward and Call Pickup Settings section, verify that you do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point.
Always disable (turn off) Secure Real-Time Transport Protocol (SRTP) when configuring a Cisco Unified
Communications product. You can disable SRTP for a specified device or for the entire Unified Communications
Manager:
For a specified device-Choose Device > Phone. ln the Find and List Phone page, select the required phone device. Ln the Phone Configuration page for the selected phone, scroll down to the Protocol Specific lnformation section.To turn off SRTP on the phone device, select any one of the Non Secure SCCP Profile auth by choices from the drop-down list in SCCP Phone Security Profile or SCCP Device Security Profile field.
For the entire Unified Communications Manager cluster-Choose System > Enterprise Parameters. ln the Enterprise
Parameters Configuration page, scroll down to the Securities Parameters section, to verify that the corresponding value for the Cluster Security Mode field is 0. This parameter indicates the security mode of the cluster. A value of 0 indicates that phones will register in nonsecure mode (no security).
The Unified CCX extension for the agent must be listed within the top 4 extensions on the device profile. Listing the extension from position 5 on will cause Unified CCX to fail to monitor the device, so the agent will not be able to log in.
Do not forward any Unified Communications Manager device to the Unified CCX extension of an agent.
Do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point.
Do not use characters other than the numerals 0 to 9 in the Unified CCX extension of an agent.
Do not configure two lines on an agent phone with the same extension when both lines exist in different partitions.
Do not assign a Unified CCX extension to multiple devices.
Do not configure the same Unified CCX extension in more than one device or device profile. (Configuring a Unified
CCX extension in one device or device profile is supported.)
To use Cisco Unified lP Phones 9900 Series, 8900 Series, and 6900 Series as agent devices, the RmCm application user in Unified Communications Manager needs to have "Allow device with connected transfer/conference" option assigned to itself.
